Should I make a complaint and an advertisement about this insurance company?

I don't know if I gone overboard on this matter. Lately I have this car accident, and the opposite party's insurance denied my claim. They only make up such excuse of "severe weather condition, and they won't contribute any payment to the damage his client caused on my vehicle." That is outrageous, and I won't simply let go of it. So, I already file a complaint on Better Business Bureau, but I don't know how much effect will that be.
I also want to make an advertisement on the social network sites about this insurance company which is CornerStone National Insurance Company, about their way to conduct business. Not long ago, I heard this person who got his guitar damaged from one of the airline handler on baggage. The airline unwilling to pay for it. Then he wrote a song and broadcast it on youtube and other social network sites about this airline. Eventually, this airline give in and compensate his loss.

Making a campaign against a company is time consuming, but it can prove to be effective. Don't back down, document what you do , whom you speak with and what they say they will/will not do. severe weather is not a reason to deny a claim.

It's sad that they will take your money and then not give you coverage in return...I had health insurance from the same company for 14 years...one day they cancelled me...I hadn't ever put in a claim...well there was this law that says that they can group people together and drop them....so I was dropped with a bunch of others that turned 50!!!! I called my senator....the govenor....the state attorney general....and I pointed out how much money they took from me over the years....I also told them that if I had taken money like that from the insurance company without giving them a product in return I would have been put in jail for theft!
